validate_x12_structure

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already provide readOnlyHint=true and destructiveHint=false, and the description's 'Read-only or local operation' mostly repeats this. The 'local operation' adds a small behavioral detail about network usage, and the alias relationship adds context, but the core behavior (validation) is already implied by the tool name and annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence that states the alias, purpose, input, and output with no wasted words. It is appropriately concise and easy to scan.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one parameter and no output schema, the description adequately covers what it does (validate), what it takes (raw X12), and what it returns (validation summary). However, it does not describe the contents of the validation summary or clarify why an alias exists, leaving a small gap in completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema fully describes the single parameter 'content' as 'Full raw EDI document text' (100% coverage). The description does not add further parameter details beyond restating 'raw X12 interchange structure', which matches the schema, so no additional value is provided.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool validates a raw X12 interchange structure and returns a validation summary. It also identifies itself as an alias for validate_edi, making the purpose explicit and distinguishable from other siblings by naming the specific function.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description says 'Alias for validate_edi' which tells the agent this tool is interchangeable with validate_edi, providing a clear usage alternative. It also notes the read-only/local nature, but does not explicitly state when not to use it or contrast with other validation/parsing tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
